Styroboard Expanded Polystyrene Wall Insulation

Styroboard Expanded Polystyrene Wall Insulation

Styroboard™ is expanded polystyrene sheet insulation ideal for coolrooms, wall, ceiling and under slab requirements and refrigeration insulation. Stryoboard is lightweight, strong, clean and easy to handle, therefore making it ideal for rendering.

Foamex Styroboard expanded polystyrene sheets is a well-proven construction material in a wide variety of building applications.

It can be used to build, insulate and decorate any building, from warehouses, businesses, factories, shops, houses and apartment blocks, to garden sheds, patios and garages.

Foamex Styroboard expanded polystyrene sheet are used as:

• Insulation of flat and pitched roofs, under floors and inside wall cavities
• External and internal wall insulation to protect against the effects of temperature and noise
• Void form system (Foamex Diamond Pods™) for pouring domestic and commercial concrete slabs
• Architectural improvements such as architectural profiles, columns, shapes, keystones, gables, fence caps and external wall sheets, which can be rendered to match new or existing building designs.
• Styroboard is available in any thickness from 10mm to 600mm. Non standard sized sheets and varying thicknesses are readily available and cut to your specific order.

Standard Sheet Sizes

Our standard size sheets are as follows and can be ordered in varying thicknesses.

• 5000mm x 1200mm (NSW)
• 2500mm x 1200mm (NSW)
• 4800mm x 1200mm (VIC)
• 2400mm x 1200mm (VIC)

Thermal properties

Styroboard expanded polystyrene sheets can be used for Steel stud, timber stud, concrete and masonry buildings, providing an efficient and economical solution for insulation.

As the Styroboard expanded polystyrene sheets is often used on the outside of the wall, stud cavities are maintained closer to room temperature, reducing the risk of surface and cavity condensation. The thermal mass advantages of concrete and masonry walls are also improved.

Styroboards thermal conductivity for our expanded polystyrene sheet grades is shown in the reference below.

Styroboard and the effects of moisture

It is recommended that an effective vapour barrier be provided in situations where significant moisture content increases are likely to occur. Styroboard is generally resistant to moisture gain, however, moisture content will affect it’s thermal performance as with all insulating material.

There is a linear relationship between Thermal Resistance (R-value) loss and moisture content increase by volume. There is an approximate 2.5% loss of R-value per 1% moisture content by volume increase (up to 20% m.c. by volume). Styroboard that has a 2% moisture content by volume, will have 95% of it’s dry R-value.

Our Environment

The manufacture of Styroboard produces no ozone depleting gases and uses no CFCs.

For each kilogram of oil used in the manufacture of Styroboard insulation, savings of up to 200kg of heating fuel can be made over the average life of a house. In turn this plays a positive role in reducing carbon dioxide emissions, and the effects of global warming.

Styroboard does not degrade into harmful substances or contaminate ground water. There has also been no reports of any harmful effects on health that could be due to a casual relationship with Styroboard.
